List Version Source flow Name there Why this flow
EF 3.1 08a91e70-3ddc-11dd-97e4-0050c2490048 polychlorinated biphenyls The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 80301299-5395-5924-876a-f65109208b59 Polychlorinated Biphenyls The CAS numbers are the same (1336-36-3); both name the same compartment.
ecoinvent 3.12 c9b97088-efc6-43c1-8d26-f78d6cdbb50b Polychlorinated Biphenyls A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.

Characterisation factors

12

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
